Move API Documentation

This api allows the user to move a document within the document tree using the parameters parent_document_id and index. If parent_document_id is not provided, the document will be placed at the top level of the document tree. index represents a zero-indexed document order relative to its siblings under the same parent. For example, if we want to put the document at top level in first position we would send parent_document_id: null and index: 0. This api also supports using a negative index to count backwards from the end of the document list, which means you can put the document in last position by using index: -1.
